To a roll/0m it may concern.-

' Be it known that l, HIRAM W. BLAisnuLL, a citizen of the United States, residing at Les Augeles, in the county of Los Angeles and State of California, have invented certain new and me al improvements in Systems for Com vcying, liistributing, and Excavating Material; and i do hereby declare the following to be a full, clear, and exact description or the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to conveyor systems, and particularly to systemsfor conveying, mixing, and distributing material; and some of the objects of'the invention are to provide such systems which will be simple in construction and positive and effective in operation. 4

Anotherobject of the invention is to arrange the conveyors in such manner as to transport the material from one receptacle to another in each row of receptacles and from one row to other parallel rows without interrupting or retarding the passage of the material from the source of supply.

A further object of the invention is to transport wet or dry material or dry 0 r moisten the same, as may be desired, while being transported, then discharge the dried or moistened material into a receptacle for treatment, then discharge the treated material to the place of deposit, or reconvey the treated material back to another receptacle for further treatment, and to accomplish the foregoingobjects by one continuous operation.

it is also an object of this invention to pro " vide means for rapidly filling and emptying bins, vats, or other receptacles, and to distribute thematerial supplied to the bin or vat evenly throughout the entire area thereof, and which can be operated to gradually feed the contents of the bin or vet to a central discharge-opening. I

A further object of the invention is to provide means for filling and empty-dug, as well as distributing, the. material'operated upon in 'a plurality of rows of vats or receptacles, and

substantially as more fully described in the following specification, and as illustrated in the accompanying drawings, forming part of this application, in which Figure l is a diagrammatic top plan view of a row of receptacles provided .with a system of conveyers and means for either drying or moisteniug the material in transit and for discharging the material from a filled receptacle. Fig. 2 is a diagrammatic side elevational View of the same. Fig. 3 is a diagrammatic top plan view of a row of recep tacles provided with a system of conveyors and means for distributing the slimeless tailings into the receptacles and discharging the same therefrom. Fig. l is a diagrammatic side elevational view of the construction shown in Fig. 3. Figs. 5 and 6 are views substantially similar to Figs. 3 and 4 with a slight difference in the arrangement of the conveyors. Fig. 7 is a diagrammatic top plan view of a plurality of parallel rows of receptacles provided with systems of conveyors and means for drying or moistening the material in transit and for discharging the dried or moistened material into and from the receptacles. Fig. 8 is a diagrammatic side elevational view of the same, and Figs. 9 and 10 are detail views of one form of distributor that may be employed.

Similar characters of reference designate corresponding parts. throughout the several views.

Referring to the drawings, and particularly to the construction illustrat ed inFigs. 1 and 2 thereof, the reference character 1 designates receptacles or vats, which are here'illustrated whereon travel wheels 3, supporting traveling structures or bridges 4c and 5, respectively, supporting an excavator 6 and a centrifugal distributor 7, both whereof are constructed to be moved along said tracks over the receptaclcs 1, as will be readily understood. The material operated upon may be from the tailings-pond or from the dry-crushing mill, and if from the former it will require to be dried before being delivered to the treating-receptacles 1, and if from the latter it will be necessary to moisten the dry and finely-divided material to prevent loss ofthe small and valu able particles in dust. Therefore the material may be brought from the tailings-pond, if wetor moist material is being handled, upon an endless belt or other conveyor 8, arranged to discharge the wet material into a receivinghopper 9 of a mixing-receptacle 10, where it is agitated or mixed while subjected to the action of a drying agent and is discharged from the mixing-receptacle upon a main end- IO less conveyer 11, having an inclined portion 12, and the main conveyer 11 passes up over -a tripper 13 upon one end of the traveling structure or bridge 5, whereon is mounted an auxiliary or cross conveyer 14, constructed- 5 to receive the dried material from the main conveyer 11 as. the same passes up over the gripper 13' and conveys the material so received to a centrifugal distributer 15, also carried by said bridge, which distributes the ma- IO terial discharged thereinto by said cross-conveyer into the receptacle or vat 1, over which the traveling structure or bridge 5 is at the time located. Afterthe first receptacle or vat shall have been thus filled the bridge 5 *5 may be progressed by machinery or by hand along the tracks 2 until it isbrought over or above the next succeeding receptacle or vat;

but during the removal of the bridge 5 from one vat to another the'supply of material will 3 be temporarily discontinued. When the material comes from a dry-crushing mill, it is transported to the mixing-receptacle by the conveyer 8, as before explained; but instead of being mixed therein while subjected to the action of a drying agent it is sprayed with liquid and thoroughly mixed therewith, after which the mixed material is discharged upon the main conveyor 11, which discharges upon the 'cross-conveyer 14, that discharges 4 into the centrifugal distributer 15, substantially as before stated. The centrifugal dis tributer discharges the material uniformly within the vat, where the contents is subjected to treatment while the succeeding vat is filled in the manner before described. When it is desired to remove the treated material from. the vat which has been thus filled, it is only necessary to move the traveling structure or bridge 4 over or above the tank to be emptied 5 and startthe excavator 6, carried thereby,

whereupon the material is discharged therefrom upon an endless lower or discharging conveyer 16, arranged to run in either direction, so as to convey the material to the waste- 5 5 dump or to convey it to an elevating-conveyor 17, which discharges the treated material a second time into the mixing-reccptacle 10 to be again dried and returned in the manner before described to the vats for retreatment.

6O Adverting now to the construction illustrated in Figs. 3 and 4 of the drawings, there this construction the main conv'eyer 11 does not reach a plane above the vats until beyond the second vat, Fig. 4. Therefore the first and second vats cannot be filled by the centrifugal distributer 7, as in the construction iirst described. The first and second vats are filled by a Butters distributer, receiving the material from the launder or in any other desired manner, and the vats thus filled are emptied by the excavator 6, the contents thereof being discharged upon an inclined conveyer '16, discharging upon a cross or elevating conveyer 17, which discharges upon the main conveyor 11, before mentioned, to return the treated material to the vats for further treatment. All of the vats except the first and second vatsjust described may be filled by means of the centrifugal or other distributer 7 and parts operating therewith, and such other vats maybe discharged of their con- 5 tents by means of the excavator 6, which causes such contents to fall through the bottom of the vat upon an endless conveyer 18, which either transports to the waste-dump the material discharged thereon or discharges such material upon an inclined conveyer 16, discharging upon a crossconveyerl7, emptying upon the main conveyer 11, which returns the material to the vats for retreatment.

Figs. 5 and 6 iilustrate asubstantially similar construction, with theexception that the discharging-conveyer 16 is made shorter in this construction and the inclined conveyer' 18 is lengthened, Fig. 6, and the treated ma terial can be discharged from the vats upon said discharge-conveyer, which can be arranged to transport the same to the wastedump or to discharge it upon the inclined conveyor 18, which discharges upon the elevating-conveyer 17, that returns the treated 5 material to the main conveyor 11, as before explained.

In Figs. "1' and 8 of the drawings there is illustrated a piur lity of parallel rows of vats 1, with a track d disposed on each side of IIO each row and parallel therewith, on which travels thd bridge 4, supporting the excavator 6-and the bridge 5, carrying the centrifugal distributor 7 and the auxiliary or cross conveyer 14, discharging into said distributer shown in Fig. 7 as constructed in two parts or section, in order to receive the material; from the main conveyer 11 at either end of the bridge 5, according to the position of the bridge, as will be hereinafter more fully explained. Upon the tracks 2 travels another structure or bridge 19, supporting a Butters distributer or equivalent device receiving material from the launder and discharging the same into the first two vats, substantially as shown in Fig. 7 ofthe drawings. The mate rial from the tailings-pond is discharged from an endless conveyer 8 into the mixing-receptacle 10, which discharges the mixed material upon the main conveyer 11 and the latter traveling adjacent thereto, a cross or auxi in turn discharges upon the auxiliary conveyer H, that empties the material into the centrifugal distributor 15, by which the material is distributed unilorn'ily within the vat in the manner bet'orei stated. After the tirst two vats shall have been tilled by the traveling Butters distributer or the other vats shall have been tilled by the traveling centrifugal distributor then the said distributers will be moved out of the way and the traveling excavator 6 brought into position over the tank to be emptied and the contents discharged from said tank by said excavator upon the continuous discharge-conveyer 16, arranged to transport the material to the waste-dump or discharge it upon the elevating-conveyer 17 to be returned to the mixer, from which it is redelivered to the vats by the main conveyer 11, substantially as before stated.

When a plurality of rows of vats are employed, as shown in Fig. 7, cross-tracks. 20 are arranged at the discharging end of the rows of vats, and mounted to travel on said tracks is a transfer table or platform carrying short transverse a l-sections 21 to receive and support the wheels 3 of the distributor or excavator bridges when it is desired to transfer either of said bridges from one row of vats to the other, as will be readily understood. By means of this construction only one excavator and one centrifugal distributer are required for any number of rows of rats, as either can be run upon the transfer-table and conveyed to any desired row of vats. When the centrifugal distrilmter-lu'idge is transferred, a traveling trippcrZQ' is employed for the main conveyer-11 and is independent of the bridge or traveling structure earryiugthe centrifugal distributor in order to permit of the transfer of the latter from one row of vats'to the other.
